Wireless integrated-media communications can be realized through a variety of wired and wireless transmission media such as radio waves, co -axial cables, radio electric power transmission, wireless voice/video appreciation etc. Our laboratory aims to construct user-oriented information-communication systems for backbone core networks, mobile communication networks, and ubiquitous home networks. For that purpose, we research technologies of the network layer, the media access layer, and the physical layer and their integration by taking advantage of the nature of individual transmission media.
